Hi all, Does this seem like the morally-correct thing for promises to do in the presence of parameters?
-> (define x (make-parameter 3)) -> (define y (parameterize ((x 4)) (delay (list (x))))) -> (parameterize ((x 5)) (force y)) '(5) I was expecting '(4), because I felt that delay should be more like let than lambda, if you see what I mean. That is, I expected that (delay expr) and (let ((foo expr)) (delay foo)) should be pretty similar except for exactly when expr gets evaluated.
